[Lex Computer & Tech Group/LCTG] Nuclear fusion...

[carllazarus at comcast.net]

I read that “The LLNL said a team at its National Ignition Facility (NIF) conducted the first controlled fusion experiment in history on December 5, achieving what is known as "scientific energy breakeven."”

What is counted in “scientific energy” and what does it omit?

All,

 

Be careful about Hype versus simple reality

 

Yes it does appear that LLNL National Ignition Facility may have hammered a poor defenseless target pellet into producing more fusion energy than was absorbed by the pellet

so technically Q>1 [about 1.2]

 

BUT -- and I'll admit a bias toward Magnetic Confinement Fusion -- the Energy used to produce the Energy delivered to the pellet was not part of the calculation

 

While Magnetic Fusion with Superconducting Magnets in a Tokamak configuration probably need Q>2 to be a credible Eureka Moment -- The energy needed to fire the lasers probably needs a Q>30
